Android Question Odd Canvas Behaviour - Possible Bug?

[Gary Milne]

I'm using a Scrollview for configuring Application Settings. If the Height is set to

pnlSettings(i).Height = 388%y

it display normally


If I increase the Height beyond this ie

pnlSettings(i).Height = 389%y

then everything that is written to the Canvas disappears leaving just the Views visible


This is true in both Release and Debug mode. Is there some inherent limit to a Canvas or Scrollview that is at play here?

What is the value of Log(389%y)?

ScrollView doesn't have any limit. Creating a Canvas for a very large image may require too much memory.

It was 3.89 times the screen height on a current generation Nexus so perhaps it was a big canvas that was the problem. I have changed my routine to use a Tabhost and smaller canvases which is just fine as a substitute.
